The all-new Shimano Ulterga 6800 11-speed is here, and the cassette's 11th cog promises you more gearing options for spinning, sprinting, or climbing. And don't forget that the new Ultegra is rolling out with new gram-shaving technology such as slimmer, stronger cogs, and slightly narrowed cog spacing allowing for less material use, and smoother, more precise shifting. And for you mountain riders and touring goers, there is an 11-32t version of this cassette available here at Nashbar (product #SH-CS6800).
